Product Description
Silicon carbide is a non-metallic mineral product made at 1800ºC and above with quartz sand and anthracite or petroleum coke as basic raw materials. It can increase the carbon, silicon, and manganese absorption rates, and has completely replaced previously-used silicon iron and high-carbon manganese. It not only reduces costs but also improves the overall economic benefits of steelmaking. It is an important raw material widely used in metallurgical deoxidation and production of refractories, electronics, machinery, and molds.

Due to its stable chemical properties, high thermal conductivity, low thermal expansion coefficient, and good wear resistance,silicon carbide has many other uses besides being used as abrasives. For example, silicon carbide powder is applied to the impeller or cylinder of a water turbine by a special process. The inner wall can improve its wear resistance and prolong its service life by 1 to 2 times; the high-grade refractory material made of it has heat shock resistance, small size, light weight, high strength and good energy-saving effect. Low-grade silicon carbide (containing about 85% of SiC) is an excellent deoxidizer.It can speed up the steelmaking speed, and facilitate the control of chemical composition and improve the quality of steel. In addition, silicon carbide is also widely used to make silicon carbide rods for electric heating elements.
Applications for black silicon carbide
1. as an abrasive, it can be used as a grinding tool, such as grinding wheel,oilstone,grinding head, sand tile, etc.
2. As a metallurgical deoxidizer andexotic material.
3. High-purity single crystal, which can be used for manufacturing semiconductors and manufacturingsilicon carbide fiber.
4. It can be used as deoxidizer for steelmaking and modifier for cast iron structure, and as raw material for manufacturing silicon tetrachloride.
5. It can be used as high temperature indirect heating material.
6. Anti-wear lubricants, structural coatings, functional coatings, protective coatings, absorbing materials, stealth materials, etc. in the industrial field
7. Glass polishing, rubber tires and other rubber products, high-performance brake pads, product anti-wear lubrication, high-hardness wear-resistant powder coatings;
8. High-performance structural ceramics (such as rocket nozzles, nuclear industry, etc.), which can be used as ceramic knives, cutting tools, measuring tools, molds; special-purpose structural ceramics, functional ceramics, composite ceramics, engineering ceramics;
9. Protective armor for tanks and armored vehicles;
10. Igniter; electric heating element for electrical industry, far infrared generator.generator.
